Your entire residence should be a refuge that’s warm and toasty in the cold months and cool and comfortable in the summer. However, owners of some multi-level residences find the upper floor is stubbornly hotter or colder than the first floor.
This could simply be due to the fact most thermostats in a house are on the ground floor, which is where people spend the most time—in the living room, kitchen, etc.—so as a result they tend to set the temperature according to how it feels on the first floor.
However, temperature discrepancies between the upstairs and downstairs could also be caused by trouble with your HVAC system. Some of these difficulties can be solved somewhat quickly while others might call for more extensive and costly fixes. Here, the professionals at Olde Towne Heating & Air will help you figure out why the upstairs of your home is hotter than downstairs, or vice versa.
Why Is My Upstairs So Hot?
The phenomenon of the upstairs of a two-story home getting hotter than the downstairs can be traced to several factors. First, heat rises, so it’s common for the second floor of a home to get hotter than the ground floor. Lack of insulation in the attic or roof can exacerbate this issue by letting heat transfer from the roof into the upstairs rooms.
Another common reason is that the air conditioning is not strong enough to cool the entire home, causing it to have difficulty cooling the upstairs adequately.
To deal with these issues, homeowners could put in additional insulation in the attic and make sure their home has sufficient ventilation. If there’s a question of whether the AC is the proper size for the home, call an experienced HVAC company like Olde Towne Heating & Air inspect the unit. A knowledgeable professional also can help select a unit that's better suited for your home if you want air conditioning installation or replacement.
Why Is My Upstairs Colder/Not Heating?
When the downstairs of your home is warm, but it’s freezing upstairs, that could result in a frosty night for anyone whose bedrooms are on the upper floor. The most common reasons an upstairs not heating like it is supposed to are the insulation levels and the ductwork.
Inadequate insulation allows cold air to leak through the home’s attic or walls and contribute to heat loss, resulting in colder temperatures on higher floors. It’s crucial to make sure your home has a deep, level layer of insulation in the attic and adequate insulation in the walls to keep the cold out and the heat inside.
The ductwork in a home plays a very important role in circulating conditioned air throughout different areas of the building. However, troubles with the ductwork can cause the upstairs being colder than the downstairs. A frequently reported explanation for this is improper airflow balance. The ducts may not be the proper size or design, creating an uneven distribution of air between the floors. This can cause more warm air to flow downstairs, causing insufficient airflow—which is the heated air—on the upper level.
Another potential problem area in the ductwork is the placement of the supply and return vents. If there are fewer vents on the upper story or they aren't well installed, it can limit air circulation and cause substandard heating or cooling. Additionally, leaks or gaps in the ductwork can lead to air loss, lowering the overall efficiency of the HVAC system and making the temperature difference more pronounced.
To understand why the upstairs is colder than the downstairs, homeowners should hve their ductwork checked by experienced professionals like the team at Olde Towne Heating & Air to identify any imbalances, leaks or inadequacies. Sealing leaks and adding new vents or adjusting existing ones can help enhance airflow and ensure a more even temperature balance between the upstairs and downstairs.
Fixing the Hot or Cold Upstairs Problem?
If your upstairs is hotter or colder than the ground level of your home, an HVAC zoning system could be a highly effective solution.
An HVAC zoning system divides the home into different zones, which each have their own thermostat and damper system so the homeowner can control the heating or cooling of each zone.
This system can be very useful in situations where the upstairs of a multi-story home is very hot or too cold while the main floor is comfortable. By setting up a zoning system, homeowners can manage the temperature independently in each zone, enabling them to address specific hot or cold spots effortlessly.

Why Is it So Humid Upstairs?
In addition to the upper story being hotter or colder than the rest of the house, another challenge in multi-floor homes is when the upstairs is more humid than the first floor.
A typical cause for excess upper floor humidity is poor ventilation on the upper floor, which can cause greater humidity levels. As is often the case with temperature differences between floors, poor insulation or sealing in the attic or walls may permit warm, humid air from outside the house infiltrate the upstairs rooms. Plus, if there are any leaks or plumbing problems on the upper floor, that can also create extra moisture in that area of a home.
To manage humidity problems, homeowners can increase ventilation by installing fans or opening windows to promote airflow. Appropriate levels of insulation in the attic and better sealing the attic and walls can help protect against external moisture from entering the upstairs. Finding and repairing any leaks or plumbing issues is also critical.
Depending on the levels of moisture found in the home, a whole-home dehumidifier could be another worthwhile tool to reduce humidity in your home.
